The recovery is separate from the firmware. So I don't see why it wouldn't be possible. Root on the other hand I wouldn't know but I suppose the SuperSU beta zip file flashed with custom recovery would get the phone rooted.

If it was a kernel being flashed then that would matter as it affects the firmware (as it replaces the stock kernel).

Yep. You can install a custom recovery, even if you accidentally wipe your system, the custom recovery will still be there. (I have experience) I think that, if you can find the right supersu zip file for your phone, you should be able to root your phone.

I tried to install the custom recovery using adb, however my phone can't be detected ?

Did you install with with fastboot? or from within the phone? Because you have to reboot to recovery pretty much right after flashing it. Try re-flashing twrp from inside the phone with flashify, then reboot to it immediately afterwards. (Get the 3.0.2-0 (or higher) version for your phone)

Yes installed with fastboot, I manually booted into recovery (volume up + power button) right after flashing it. I thought flashify requires root ??

Wait, you updated to 7.0 without root? Did you use the normal updater? Because if so, try finding a way to downgrade again. Maybe that will work

Yeah, I just flashed the update using the dload method. The main reason I want to install TWRP is so i can downgrade. I've tried using the dload method to downgrade however it doesn't work.

Same problem here, I installed a leaked Nougat beta for the Honor 8 via TWRP and when I tried to get back to TWRP it wouldn't let me. I've tried to flash it again via fastboot but I can't boot into it :/

I have never had this kind of problem before. If you tried a cold boot (Hold volume up + power), try typing "adb reboot recovery" instead (or the other way around, if you've done that)
